[Word2Vec: Warning対処] DeprecationWarning: Call to deprecated `__getitem__` (Method will be removed in 4.0.0, use self.wv.__getitem__() instead).

DeprecationWarningが出たので対処法メモ

cofirm.py

from gensim.models import word2vec

model = word2vec.Word2Vec.load("hoge.model")
vec = model["queen"]
print(len(vec.tolist()))

$ python3 confirm.py
confirm.py:7: DeprecationWarning: Call to deprecated `__getitem__` (Method will be removed in 4.0.0, use self.wv.__getitem__() instead).
  vec = model["queen"]
300

警告が出てくるので，
プログラムを以下のように変更する．

confirm.py

from gensim.models import Word2Vec

model = Word2Vec.load("hoge.model")
vec = model.wv['queen']
print(len(vec.tolist()))

$ python3 confirm.py
300

警告が消えました．(´▽｀)
